甲醇合成反应热力学分析及实验研究

THEORETICAL ANALYSIS AND EXPERIMENTAL STUDY ON THERMODYNAMICS OF METHANOL SYNTHESIS

比较了近年来文献中甲醇合成反应平衡常数的各种计算方法 ,采用固定床反应器在反应温度为 2 30～ 2 70℃和反应压力为 5～ 8MPa的条件下对甲醇合成反应热力学进行了实验研究。结果表明 ,不同计算方法的预测结果存在较大的差异 ,而采用 Reid的热容数据及 SRK方程得到的计算结果与实验结果吻合很好 。

In this paper, various methods in calculating equilibrium constant of methanol synthesis reaction were reviewed and compared. Experimental study on the thermodynamics of methanol synthesis was conducted in a fixed-bed reactor. The reactor was operated under a temperature range of 230 [similar to] 270°C and a pressure range of 5 [similar to] 8MPa. The results showed that there is considerable difference among values of the equilibrium constants obtained from different calculation methods. The method employing Reid's thermodynamic data and Soave-Redlich-Kwong (SRK) equation (EOS) can yield result best agreeing with the experimental data.
